CacheLink: Functional KV Transport for Zero-Prefill Cross-Model Context Handoff
Haomiao Qiu, Yining Tang, Zijia Song +3
KV caches make long-context serving efficient by reusing past computation, but model switching breaks this reuse and forces the receiver to prefill the context again. We study \emp…
Constrained Reinforcement Learning for the Dynamic Inventory Routing Problem under Stochastic Supply and Demand
Umur Hasturk, Albert H. Schrotenboer, Kees Jan Roodbergen +1
Green hydrogen has multiple use cases and is produced from renewable energy, such as solar or wind energy. It can be stored in large quantities, decoupling renewable energy generat…
Hydrogen Network Expansion Planning considering the Chicken-and-egg Dilemma and Market Uncertainty
Sezen Ece Kayacık, Beste Basciftci, Albert H. Schrotenboer +2
Green hydrogen is thought to be a game changer for reaching sustainability targets. However, the transition to a green hydrogen economy faces a critical challenge known as the `chi…
Dual Sourcing of Green Hydrogen: Balancing Local Production with Stochastic Capacity and Import with Random Yield
Sezen Ece Kayacik, Albert H. Schrotenboer, Iris F. A. Vis +2
Green hydrogen is a critical component for achieving the European Union's 2050 net-zero emissions goal. However, ensuring a reliable and stable supply is challenging, particularly…
On feasibility cuts for chance-constrained multicommodity network design problems
Niels A. Wouda, Ward Romeijnders, Evrim Ursavas
Problem definition: We study efficient exact solution approaches to solve chance-constrained multicommodity network design problems under demand uncertainty, an important class of…
Adaptive Multistage Stochastic Programming
Sezen Ece Kayacık, Beste Basciftci, Albert H Schrotenboer +1
Multistage stochastic programming is a powerful tool allowing decision-makers to revise their decisions at each stage based on the realized uncertainty. However, in practice, organ…
Multi-period Stochastic Network Design for Combined Natural Gas and Hydrogen Distribution
Umur Hasturk, Albert H. Schrotenboer, Kees Jan Roodbergen +1
Hydrogen is produced from water using renewable electricity. Unlike electricity, hydrogen can be stored in large quantities for long periods. This storage ability acts as a green b…
Stochastic Cyclic Inventory Routing with Supply Uncertainty: A Case in Green-Hydrogen Logistics
Umur Hasturk, Albert H. Schrotenboer, Evrim Ursavas +1
Hydrogen can be produced from water, using electricity. The hydrogen can subsequently be kept in inventory in large quantities, unlike the electricity itself. This enables solar an…
Reliable Reserve-Crew Scheduling for Airlines
Albert H. Schrotenboer, Rob Wenneker, Evrim Ursavas +1
We study the practical setting in which regular- and reserve-crew schedules are dynamically maintained up to the day of executing the schedule. At each day preceding the execution…
A two-step approach to Wasserstein distributionally robust chance- and security-constrained dispatch
Amin Maghami, Evrim Ursavas, Ashish Cherukuri
This paper considers a security constrained dispatch problem involving generation and line contingencies in the presence of the renewable generation. The uncertainty due to renewab…
Towards Low-carbon Power Networks: Optimal Integration of Renewable Energy Sources and Hydrogen Storage
Sezen Ece Kayacık, Albert H. Schrotenboer, Evrim Ursavas +1
This paper proposes a new optimization model and solution method for determining optimal locations and sizing of renewable energy sources and hydrogen storage in a power network. W…
Green Hydrogen Plant: Optimal control strategies for integrated hydrogen storage and power generation with wind energy
Arjen T. Veenstra, Albert H. Schrotenboer, Michiel A. J. Uit het Broek +1
The intermittent nature of renewable energy resources such as wind and solar causes the energy supply to be less predictable leading to possible mismatches in the power network. To…
An Integrated Optimization Framework for Multi-Component Predictive Analytics in Wind Farm Operations & Maintenance
Ilke Bakir, Murat Yildirim, Evrim Ursavas
Recent years have seen an unprecedented growth in the use of sensor data to guide wind farm operations and maintenance. Emerging sensor-driven approaches typically focus on optimal…
